| 20120080125 | LINK CHAIN SUPERIOR IN LOW TEMPERATURE TOUGHNESS AND HEAT TREATMENT METHOD OF THE SAME - The present invention provides a link chain superior in low temperature toughness comprised of low carbon steel, said link chain characterized in that two-stage high frequency quenching-tempering is performed to give a link chain which has a martensite single phase structure, has an austenite grain size of 9 to 12, further contains in said structure a precipitate comprised of 40 nm or smaller TiC in 90% or more and 80 nm or smaller Ti(C,N) in 10% or less, contains AlN in not more than 0.0003%, and has a −40° C. Charpy impact value of at least 45 J. | 04-05-2012 |
| 20110066335 | TRAVELING CRANE OPERATION CONTROL APPARATUS AND METHOD - To provide a traveling crane operation control apparatus and method enabling an operator to operate a traveling crane quickly and accurately by one hand and by a motion of his or her body with a controller worn thereon, without the need to gaze at his or her hand, and also allowing variable-speed control and fine speed control of each drive unit. | 03-17-2011 |
| 20100127818 | HOISTING MACHINE - A hoisting machine is provided that is capable of efficiently dissipating heat generated from an inverter incorporated in the hoisting machine main body into the surrounding air with a simple structure and hence capable of performing high-frequency operation. | 05-27-2010 |
| 20090275435 | Link Chain Superior in Low Temperature Toughness and Heat Treatment Method of Same - The present invention provides a link chain superior in low temperature toughness comprised of low carbon steel, said link chain characterized in that two-stage high frequency quenching-tempering is performed to give a link chain which has a martensite single phase structure, has an austenite grain size of 9 to 12, further contains in said structure a precipitate comprised of 40 nm or smaller TiC in 90% or more and 80 nm or smaller Ti(C,N) in 10% or less, contains AlN in not more than 0.0003%, and has a −40° C.
